Touch panel

1. A touch panel, comprising: a transparent substrate; a plurality of electrodes and traces on the transparent substrate, the traces connecting the electrodes to transmit signals; and a first ground ring and a second ground ring on the transparent substrate and surrounding the electrodes and the traces, a plurality of bridges connecting the first and the second ground rings, the bridge comprising at least one electrostatic discharge tip to enhance a local electric field strength and to initiate electrostatic discharging, wherein the first ground ring and the second ground ring are separated by a space of atmosphere so that the bridges across the space of atmosphere initiate electrostatic discharging toward atmosphere environment.

2. The touch panel of claim 1 , wherein a shape of the bridge comprises a dual triangles with two connecting tips.

3. The touch panel of claim 1 , wherein the electrode comprises a structure of conductive material, the conductive material comprises indium tin oxide (ITO), indium zinc oxide (IZO), Al-doped ZnO (AZO) or antimony tin oxide (ATO), nano-silver or nano-copper.

4. The touch panel of claim 1 , wherein the grounding ring comprises indium tin oxide, indium zinc oxide, aluminum zinc oxide, or antimony tin oxide.

5. The touch panel of claim 1 , wherein a shape of the bridge comprises a geometric shape which can increase the local electric field strength.

6. The touch panel of claim 1 , wherein the touch panel comprises a one glass substrate touch panel or a one film substrate touch panel.
